FAH clients hanging

[vertica]

Hey all, need some help.

Moved my pc to uni today (dont think this is the issue!)
but this afternoon, my FAH clients are playing up

WUs are processed in the normal time, sent back to stanford upon completion and points are acredited.
The clients then connect to the work server and hangs as below: (note: the short time for the upload is due to my 80Mbps upload speed in my uni flat)

[17:39:44] + Attempting to send results [April 19 17:39:44 UTC]

[17:39:51] + News From Folding@Home: GPU folding beta
[17:39:51] Loaded queue successfully.

At this point it hangs and will not move.

Restarting the client doesn't solve the problem.

Only solution i've got atm is to delete all work and queue files once the client has hung, then restart it. The client then downloads a new WU and continues cruncing until the next dwnld, then hangs at 'Loaded queue successfuly' again.

I cant be deleting these files after every WU!

Initialy I thought firewall, proxy settings etc, but as the clients can download cores and WUs, and submit completed WUs, its not this.

anyone got any ideas?

TIA
EDIT: I dont yet know if this exclusive to my GPU clients, i will find out in an hour when my SMP unit finishes...

Gave up and just reinstalled all my clients
This didnt't work

Finally found what was causing this:
The main client exe's were in the programfiles folder, althoguh they've been running fine in there for 8 months, yesterday kaspersky decided to halt the processes when the tryied to download files (despit them being in all the exclusion list in the firewall and AV).

Seem to remember reading somewhere that programfiles has special access conditions on it, so i tried installing them outside of the programfiles folder and problem solved.
